In record cards serving for the control of sorting and tabulating machines there are usually provided a plurality of adjacent record columns. Accordingly, in such record cards only a single I longitudinal row of record columns is provided and for this reason perforation of such cards may be effected under the control of a single set of keys corresponding to a single record column, in one of the following ways: In machines having a row of punching stamps for each record column, the various rows "of, punches are brought successively under the control of said single set of keys and are prepara torily set up whereas pimching is effected simultaneously in all record columns; in machines, however, having a single row of punching stamps the record columns are punched successively by said single row of stamps which are also under the control of a single set of keys.

In order to utilize the card space to the greatest possible extent'and to maintain at the same time a favorable relation between the width and the length of the. card, a plurality- (preferabiy two or 25 three) of superpositioned rows of record columns have been provided on the card and such provislon is of particular advantage in hole combinatlonal record cards. Such superpositioned rows of record columns are termed record decks."

Accordingly, a record card of the type referred to comprises a plurality of superpositioned record decks, each deck consisting of a plurality of adjacent record columns.

However, the above mentioned perforating ma chines cannot be used for the perforation of record cards having a plurality of record decks since said machines permit only a column selection in longitudinal direction of the row of record columns while the perforation of. record cards 40 having a plurality of record decks requires in addition to the columnary selection a selection transversely to the rows of record columns, i, e. a selection of the record deck in which one or a plurality ofrecord colinnns are to be punched. Now, for said purpose perforating machines have been suggested wherein in addition to the movement of the card in longitudinal direction relatively to 'a common set of punching stamps, the selection of the record decks may be effected by a transverse movement of the card which is effected by means of adaptedtoadiustthecardtransverselytothe rows of record columns relatively to said set of punching stamps; accordingly, said set of punchus ing stampsisnotonly commonto allrecord columns, but also to all record decks. In such machines, of course, said single set of punching stamps is always in operative connection with a. single set of keys controlling said punching stamps. I f

The adjustment of the recordcard in the described manner requires, however, a complicated adjusting mechanism since the latter must per- 'mit movement of the card in two directions at a right angle to each other and yet the card must correctly be presented to the punching stamps since it is of great importance for the analysis of record cards that the holes are exactly provided on the predetermined hole positions. This 15 requirement, however, can only be metwith an adjusting mechanism of the type referred to if the same is manufactured very precisely, which, of course, increases the manufacturing costs of the machine.

Another essential disadvantage of said known way-to perforate cards having a plurality of record decks must be seen therein, that due to the movement of the card for deckselection the dimensions of the machine are influenced in a 25 very unfavorable manner, particularlyflif record cards having more than two record decks are handled since there must be sufllcient space for the movement and adjustment of the card longltudinally and transversely to the common set of 3 punching stamps.

The main aim of the present invention is to overcome the above mentioned disadvantages and to provide a novel and eflicient machine with small dimensions for record cards having a plu- 35 rality of record decks.

To attain said purpose, it is the main object of the present invention to provide a punching machine comprising an individual set of punching means foreach record deck and a common set of keys adapted to govern said punching means column by column, and shifting means common to all keys of said set of keys for governing selectively any one of said sets of punching means by said common set of keys. 5

Another object of the invention is to provide in a machine of the character referred to punch selecting means through which said punching means may be governed by said single set of keys and still another object of the invention is to pro- 50 vide an individual set of punch selecting means for each set of punchingmeans.

A further object of the invention is to provide a machine of the character referred to having a single row of punching stamps for each record 5s deck and means for moving the card and the stamps relatively to each other upon key actuation.

Still a further object or the invention is to provide a machine of the character referred to in a machine having an individual set of punching stamps for each record deck, a distance between said sets of punching stamps in'the direction of superpositioned aligned record columns,

said distance being larger thanthe distance be- Lil tween adjacent punching stamps of each set in the same direction.

A further object of the invention is to provide sidewardly extending projections on the-punching stamps on which projections engage springs adapted to keep the punches in their normal position. I 1

A further object of the invention is to provide a machine of the character referred to having a set of numeral keys and a set of letter keys both sets of keys being adapted to be commonly connected by said shifting means to the punching means for any record deck.

Another object of the invention is to provide an electrical machine of the character referred to whichprovides a set of punch selector magnets and a punch actuating magnet for each record deck. If the invention is applied to machines wherein the punches are depressed simultaneously with the actuation of a key, only a set of punching stamps for a single column of each record deck must be provided which sets may be selectively governed by the common set of keys whereas in machines in-which all hole positions of a card or deck are punched simultaneously, punching stamps must be provided for each hole position of each record deck if the present invention is applied. Of course, the invention may also be used in connection with machines having key controlled punch selectors.

Further objects and advantages of the invention will be seen from the following specification and the claims. i

A preferred embodiment of the invention will now be described in connection with the accompanying drawings.

Fig. 6 is a' section through the switch shown in Fig. 5.

Fig. 71s a detail view showing a section through the key levers. v Fig, '8 illustrates the diagram of the machine.

The punching machine illustrated in the drawings includes a frame upon which the card may be fed step by step by means of a carriage underneath the punching mechanism. The frame is mounted upon 'a casing in which the key mechanism is arranged, under the control of which punching in each column maybe effected, whereupon the carriage feeds the next column of the card under the single row of punching stamps.

Card feed The record card I2 (Figs. 1 and 2) to be punched is fed in the bed l3 of the frame ll of the machine step by step by means of the carriagestill to be described-from the extreme right hand position to the extreme left hand position. The carriage comprises in a generally known way two end pieces I5 and I6 between which the card is positioned, and the shift bar H for the step by step movement of the carriage. Said end pieces l5 and i6 as well as the shift bar I! are fastened to the guide pieces l8 and I Qadapted to slide in grooves of the frame The control of the shift bar I1 is effected by means of an escapement 2| which is under the electromechanical control of the keys. The escapement 2| is arranged between two lipsv 22 and 23 (Figs. 2 and 3) and is held by means of two springs 24 and 25 in engagement-with the teeth of the shift bar I1 in such a way that normally the left tooth of the escapement 2| is in engagement with the teeth of the shift bar I! and the spring 21 is strong enough to counter-balance the action of spring 25 and member 26 which tends to draw the carriage to the. left. The escapement is guided by means of a slot by a pin 21 provided upon the lip 22, and is drawn against the stop pin 28. If the carriage is to be fed for one step to feed the next column of the card under the punching stamps, the magnet 29 will be energized whereby the escapement 2 will be rocked in counterclockwise direction (Fig. 2) about the pivot 21 so that the right hand tooth of the escapement2| engages the toothed bar I1, however, preventing shifting of the same. As soon as the magnet 29 is deenergized, the spring 24 will draw the escapement' 2| back to its homeposition and then. the left-tooth of the escapement 2| will come .iustbehind a tooth of the bar so that the spiral spring arranged in the casing 30 will draw the toothed bar ll by means of the member 26 to the left until the next steep edge of a tooth of the bar I1 is stopped by the left tooth of the escapement 2| in whichimmediately run back to its home position, the

magnet 3| (Fig. 3)provided on the lip 23 will be energized and the same will attract its arma ture 32 fastened to the escapement. against the action of springs 24 and 25 (see Fig. 2) so that the escapement 2| ismoved downwardly and en-.

tirely out of engagementwith the toothed bar II. the pins 21, and 28 serving then as guides for the escapernent- Thereupon the carriage is drawn tions. 15

Cal

a bell crank lever 46 and the various bell crank under the action of the spring provided in casing 30 to its extreme left hand position.

If the carriage is in the extreme right hand position, the first record column of each of both decks of an inserted blank card is just under the row of punching stamps and if the carriage is in its extreme left hand position the last'recrd column of each of both decks is under said stamps. In the recordcard l2 shown in Fig. 1

there .are provided two decks above one another, each deck containing-depending upon the meaning of the different fields of the cardscertain letter and numeral data represented by perfora- The card in Fig. 1 is not divided into fields of certain meaning and the perforations are only given as examples. Since the application of perforated record. cards for the control of sorting and tabulating machines is well known, it seems not to be necessary to explain said application more in detail.

Punching mechanism The record card I2 is fed between the matrix 34 fastened on theframe l4 (Figs. 1 and 3) and between a block 35 carrying the punching stamps. By depressing the punching stamps either singly or in different combinations, the card may be punched in the upper or lower deck. The blockv [the perforation of the lower deck of the card.

Like parts which are provided for each deck individually, will be designated in the following specification generally with the same reference numbers and, if necessary, the parts being provided in the upper deck will be designated by one and the parts being provided in the lower deck will be designated by two indexes. Thus for instance, the punching stamps are usually named in the specification by 33, but thereby I mean the punching stamps 33' of the upper as well as the punching stamps 33 of the lower deck and this index designation is provided conformably for all parts being separately coordinated to each of both decks, such as for instance for the selector magnets, the punch magnets and so on. The matrix 34 is provided opposite the punching stamps 33 with corresponding holes into which said stamps may pass when the card is being punched. The waste produced by the perforapermitted to move freely underneath the punch- 75 nected by means of a pin and slot connection with levers are pivotally mounted upon bars 48 and the slides 43 are normally held by springs 49 against the bar v45, in the position as illustrated in Fig. 2. The bell crank levers 46 form the armature of selector magnets 50 being provided in the same number as the punching stamps and said magnets are adapted to rock upon energization their corresponding bell crank levers 46 in counterclockwise direction (Fig. 2), thereby moving the projection 44 of the corresponding slide bar 43 under the yoke 5| (Figs. 2 and 3) of a plate 52, said yoke being under the control of a punch magnet. While to each punching stamp 33 a control slide 43, bell crank lever 46 and selector magnet 50 is coordinated, for the group of the upper six punching stamps 33' there is provided a special common punch magnet 53' and for the group of the lower six punching stamps 33" there is provided a special common punch magnet 53",.

. To each of both punch magnets 53 is a plate 52 coordinated, being pivotally mounted at 55' (Figs. 2 and 3) and having a yoke 5!; the plates are connected by means of bars 56 with armature plates 58 pivotally mounted at 51. The armature -plate 58 of each group of six stamps is normally drawn in counterclockwise direction by spring 59 so that the punching plate 52 is held in engagement with the stop support 60.

The punch mechanism provided for each group of punching Upon a punching operation, the selector magnets 50 of the upper or the lower group of punching stamps are energized either singly or in different combinations and thereby the controlling slide bars 43 are moved to the right (Fig. 2) so that the projections 44 are positioned below the yoke 5|. If a perforation is to be eifected in the upper deck, one or a plurality of slides 43 will be moved to the right under the control of the selector magnets and thereupon the punch magnet 53' will be energized Consequently, the

link connections 58'-5G'--52' will be drawn downwardly and the yoke 5| will encounter the projections 44 of all slide bars 43' which have been moved to the right, while the slide bars 43' remaining in the left position will not be encountered by the yoke 5|. Bydepressing the yoke 5|, the slides 43 which have been moved from their normal position, will be rocked slightly downwardly about the pivot 45 and the heads 39 and consequently the corresponding punching stamps 33' are depressed far enough against the action of springs 4| to punch the holes into the card. If then the punch magnet and the selector magnets are again deenergize'd, the parts return under the influence of their restoring springs in reverse time sequence to their home position. It will be seen that by energization of one punch magnet simultaneously all holes of a certain hole combination column of one deck will be punched.

It willalso be clearly seen that a similar punching operation takes place if a perforation is. to be effected in the lower deck by means of the punching stamps 33" and punch magnet 53". After the perforation is completed in one column the carriage is shifted so that the various columns of one deck may be punched one by one.-

and are held by means of springs 83' and a framewhich is still to be described, in their normal position, in which the key levers engage the upper edge of a key slot I2 provided in the casing II. The key levers are held in proper distance from one another by means of distance tubes seated upon the bar 10, but not illustrated in the drawings. The member which is adapted to hold all keys resiliently in their upper peel-- tion-in addition to the springs 83'--comprises a rigid frame including two. cross bars 18 and it which are connected at their ends by yokes I5. The bar I4 'is pivoted in bearings I8 and the springs 'IIwound on both ends around the bar I4, tend to rock the yokes I5 in counterclockwise direction (Fig. 3) so that the key levers 81 are resiliently held in their upper position by the bar I8. The yokes I8 are also connected with one another by a cross bar 18 and in the middle portion of the same is a finger I8 fastened, acting upon the contacts 88 and 8I which are insulatingly arranged from one anotherj If therefore one of the letter or numeral keys is depressed, the frame I8, 18, I8, II will be pressed downwardly against the action of. its springs TI, and the finger I8 closes at first the contact 88 and if the actuatedkey reaches its lowermost position also .the contact 8| will be closed which latter controls shifting of the carriage. The base plate 82 upon which the casing II is mounted, carries also contact bars 88 extending at right angles to the /key levers underneath the same and being adapted to cooperate either singly or in different combinations with contact fingers of the key levers. Another contact bar 85 forms the common back line for all keys. As will be seen from Fig. 3 and the detail view according to Fig. 7, on each of the key levers 81 is an insulating bar 81 fastened having on the lower side a metal bar 88 inserted therein. On the bars 88 of the K key levers are contact fingers 88 in difierent arrangement provided. The bar 88 of each key lever is provided in addition to fingers 88 with a contact finger 88 adapted to cooperate with the contact bar 88 which is common to all keys. Each of the key levers has a contact finger 88 while the fingers 88 are provided in accordance with the perforations of the hole combinational key illustrated in Fig. 1; this may be clearly seen from a comparison of the card in Fig. 1 and the circuit diagram in Fig. 8, so thatifit seems not necessary to explain this arrangement more in detail. The timing of the various parts is such that at first all fingers 88 (Fig. 3) and finger 88 of the depressed key contact the bars 88 or 88 respectively and that upon further depression of the key finally the contact 88, andonly in the lowermost key position also the contact 8| will beclosed. If the key is released again, all parts will return under the influence of the frame I8, "II, I5 to-their home position and the plate spring contacts 88, 8| will open again. The keys 88and 88 (see Figs. 1, 2 and 4) for the control of the carriage independently of anypunching operation are both similarly constructed and for this reason only one of them is illustrated in Fig. 4.

These keys are provided with a recess 82 and are therefore not held in their upper position by the frame I8, I8, I5, but a special spring 83 is co ordlnated for this purpose to each of said keys.

Upon depression of any of said keys, said frame willtherefore not be rocked and the contacts 88, 8I (Fig. 3) will remain open. To each of the keys 88 and 88 is. however. a special contact 9 and 85 respectively coordinated (see also Fig. 8)

which may be closed by a projection 88 of the remounted recessed bars, each of said bars controlling in turn a coordinated contact.

Selection of the hole combination decks 'Through the frame wall of the machine' extends a handle I88 of a. switch which is arranged in the interior of the casing II (Fig.2); said handle serves for the sclectionof the deck to be perforated. Since in the present case only two hole combination decks are provided, the switch may be shifted into any one of two different shift positions. If the handle I88 is in its upper position, the' upper hole combination deck will be perforated upon key actuation, and if the handle is in itslower position as shown in Figs. 1 and v 2, the characters will be punched into the lower hole combination deck upon actuation of the keys. The arrangement of the deck selection switch within the current circuit, will still be described in connection with Fig. 8, where the switch is shifted to the upper hole combination deck contrarily to its position in Figs. 1 and 2. The switch proper is shown more in detail in Figs. 5 and 6, where the same is shifted (Fig. 6) to its lower position lower deck).' The switch includes an. insulating plate I82 being fastened on the front wall of the casing II. Upon this insulating plate is an arched longitudinal insulating piece I88 fastened having slots I84. .On.

there are also. provided seven other contact springs I88 being in-alignment with the contact springs I81 and I88 and being separately arranged from the springs I81 and I88 and sidelips of springs vI88 lead through the slots I84 so that the spring contacts may be connected by means of screws I88 to the current circuit. Upon the shaft I8I is an arm I 88 pivotally mounted having a handle I88 which extends through the casing II (see also Figs. 1 and 2) to the outside of the .machine. n the other end of the arm I82 are seven contact springs I 84 provided being in alignment with the above mentioned springs I81 and I88.

. As may be seen from Figs. and 6, all contact springs I81 are electrically connected with the contact springs I89 by the bridging contacts I" if the handle I93 is in the lower position as shown in Fig. 6. However, if the handle is moved to the upper position, as shown in dotted lines, the contact springs I81 are free and a connection will now be established between the contact springs I89 and I88. As may be seen from. the drawings, the contact springs are slightly curved in the middle portionso that they are adapted to be resiliently moved and are securely held in position. The contact springs I89 are connected to the contact bars 84 (Fig. 3) by lines I88 (see Fig. 8), while the upper'contacts I81'are connected with the selector magnets 58" of the lower deck and the lower contacts I88 are connected with the selector magnets 58' of the upper deck. If, therefore, the lever I98 is in the lower position (Figs. 2 and 6), the lower six selector magnets 58" are connected with the contact bars 84 and are therefore inserted into the operating circuit, and consequently the lower hole combination deck will be punched while the magnets 58" of the upper deck are inoperative. If the lever I93 is shifted to its upper position as shown in Fig. 8, the magnets 58" of the lower deck are inoperative and the magnets 58' of the upper hole combination deck are connected with the contact bars 88.

Circuit diagram As may be seen from the circuit diagram according to Fig. 8, the keys 88 are provided with contact fingers 89 on those positions on which the respective character is represented by a hole according to the scheme in Fig. 1, and it will be understood that the hole positions of any of both decks as well as the fingers 89 of the contact bars 84 being coordinated to the fingers 89 are to be counted in the same order from the uppermost to the lowermost position. The contact bars 84 are connected by lines I88 with the six upper contacts I89 of the switch; consequently, if the switch is in the upper position as shown I in Fig. 8, the selector magnets 58' of the upper deck are connected with the lines I88, and in the lower position of said switch the six selector magnets 58" of the lower deck are in connection with said lines. All magnets 58' and 58" are in turn connected by a common line 91 with the upper pole of the current source I88 and the back line bar 85 which is common to all keys,

- is connected by a line 86 over resistance I I8 with the lower pole of the current source. The lowermost contact of the switch I93 connects in the illustrated position the line II8 leading to the contact ill with the line I83 leading to the punch magnet 53' of the upper deck, and if the switch is in the lower position the line II8 will be connected with line I83" leading to the punch magnet 53" of the lower deck. The contact 8| to which line I I8 is connected, is on the other hand connected to the upper pole of the current source over line II9. To the current source I88 is over a resistance III the magnet connected which is controlled by the contact 95, and also the carriage shift magnet 29 being controllable by the contact 94 as well as by the parallelly arranged contact 88. It will be seen that upon depression of the release key 89 the contact 95 will be closed thereby energizing the magnet 3! so that the carriage is permitted to return to its home position, as has been explained more in detail in a previous part of the specification. Since upon each punching operation the contact 88 is closed position so that now by the finger 19, the carriage is permitted to shift after deenergization of the magnet 29 so that the next column of the card will be fed under the punching stamps. The key 88 is only actuated if the carriage is to' be shifted step by step without effecting any punching operation.

Operation of the machine If the carriage (Figs. 1 and 2) is in the extreme left hand position, the card to be perforated is inserted into the carriage and the same is moved to the extreme right hand position so that the first column of the card will be positioned under the punching stamps 33. By positioning the shift lever I93 (Fig. 1) the upper or lower deck must then be selected for perforation; if at first the upper deck is to be punched, the shift lever I93 is moved to its upper position. It now any character key 88 (Fig. 8) is depressed, the contact fingers 89 and 98 will at first establish a corresponding connection between the bar 85 and the bars 84 contacted by the fingers 89 so that, in accordance with the contact fingers 89 of the depressed key a current circuit will be established over the corresponding selector magnets, said circuit leading, over line 88, bar 88, selectedcontact bars 84, corresponding lines I88, selector magnets 58', and finally over common line 91 back to the current source. Since the lines of the selector magnets 58 are open at I81, only the upper group of the selector magnets 58' may be energized. Upon the further downward movement of the key, the frame 13, 14, 15, 18 (Fig. 3) will close by means of finger 19 the contact 88 so that the carriage shift magnet 29 (Fig. 8) will be energized; however, the carriage is only permitted to shift after deenergization of said rnagnet and then the punching operation is already completed as will be seen from the following explanation. If the key has reached its lowermost position, the finger 19 closes also-the contact 8I thereby energizing the punch magnet 53' and causing the following current flow: from the upp r pole of the current source I88 over line I29, c -ntact BI, line H8, lowermost contact'springs I89, I94, I88, line I83, magnet 53' and line I28 to the lower pole of the current source. If the punch magnet 53' becomes energized, the yoke 52' will encounter the projections 44 of the controlling slide bars 43 (Fig. 2) whichhave been moved to punching position by the energized selector magnets 58', and the corresponding punching stamps will be pressed downwardly through the card in a combination corresponding to the meaning in the key. If then the key re-- turns under the influence of its spring 93' and of the resiliently mounted frame 13, It, 15 to its home position, the punch magnet 53' will at first be deenergized consequently to the opening of contact 8I (Fig. 8), and the coordinated punching mechanism will be restored under the infiuence of the spring 59' (Fig. 2) and the punch ing stamps 93' will return under theiniluence of their springs upon the subsequent deenergization of magnet 29 (Fig. 8) the carriage is permitted to shift consequently to the opening of contact 88. In this way any desired columns of the upper deck may be punched, and it will be seen that letters or numeral characters, as desired, may be punched in any column of the upper deck.

If then the lower deck is to be punched, the operator movesthe carriage (Figs. 1 and 2) again to the right and shifts the lever I98 to its lower the lines I88 (Fig. 8.) are II to normal position, so that,

connected with the selector magnets ""and the line H. is connected over line ill" to the punch magnet 53". If now a key 68 isdepressed, cur-' rent' circuits will be established in a similar way as hasbeen described, but now the selector magnets ill" and the punch magnet 53" of the lower .deck will be actuated. After energization of the selector magnets 50" the punch magnet 53" will be energized over lines Ill, I03" consequently to the closure of the contact Bl said lines being then connected with one another so that a hole com bination corresponding. in its meaning to the depressed key will be punched whereupon the carriage will again shift to the next column. It will be seen that in this way any or all colunms of the lower deck may be punched with any desired characters. a

The key according to which the hole combinations of the different characters are arranged is. of course, of. no importance for the present in- .vention and in the above described embodiment has one of the known hole combination keys been used. If another key is to be used, the contact fingers of the actuator keys must, of course, be provided in a position conforming to the chosen key or punching scheme.

In the foregoing explanation an electromechanical embodiment of the invention has been explained. The invention may, however, be executed as well in a pure mechanical way and also with quite 'diiferent operating means and it will be clearly seen that the same is by no means restricted to the aforedescribed or .a similar embodlment.

While there have been shown and described and'pointed out the fundamental novel features of the invention as applied to a single modiflca tion, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its cperation may be made by those skilled in the art without departing from the spirit oi. the invention, and it is the intention therefore, to read the following claims in the light of this understanding.
